CTP / Application Engineering Reference

Smart Water Bottle Magnetic Cable Engineering Example

A two-contact magnetic cable can be considered for a power-only smart bottle interface when the electronics, polarity and physical arrangement are compatible. Charging near liquids makes the complete device housing and cleaning procedure important. This is a design reference, not a claim that the pictured cable has been validated for a particular bottle.

Engineering reference only. No documented customer deployment, first-hand test report or approved application drawing is claimed on this page. Final custom values follow the agreed customer specification.

Define charging and polarity

State the device charging voltage and current, supply and return positions, cable length and the mating orientation. A USB-shaped supply end does not establish USB Power Delivery support or a negotiated charging protocol. Confirm the actual power source and device circuit before choosing a termination.

Design for liquid-adjacent use

Describe splash, condensation, washing and storage conditions separately. Determine whether the charging area must be dry before connection and how exposed contacts are drained and cleaned. Any ingress requirement applies to a specified assembly and test condition; magnetic attraction alone does not seal the bottle.

Keep the user interaction explicit

Provide the contact location relative to the base, cap or enclosure and the available cable clearance. Review mechanical guidance, reversed approach and accidental pull direction. The desired connection and release behavior must be approved with the actual housing rather than inferred from a general magnet description.
